Jim Carrey, whose lowbrow comedy "Dumb & Dumber" was a $247-million worldwide hit in 1994, said Wednesday that he has left the recently announced sequel.

Confirming to "ET Online" that he was exiting the Farrelly Brothers film, the comedian said in a statement, "I would have thought 'Dumb and Dumber To' was a no-brainer; after all it's implied in the title."

The website said Carrey, 50, grew frustrated by a perceived lack of enthusiasm for the project by the production company, New Line, and the studio, Warner Brothers.

Peter Farrelly, who cowrites and codirects with his brother Bobby, said in April: "We're getting set to shoot 'Dumb and Dumber 2' in September. It's the first sequel we've ever done and we've got Jim Carrey and Jeff Daniels back."

Neither Carrey, Daniels nor the Farrellys were involved with a poorly received 2003 prequel, "Dumb and Dumberer: When Harry Met Lloyd."
